Is there a manufactured solution? - aegrotatio - 01-03-2017

Is there a manufactured solution to power the PINE A64 from the Euler bus?

It sounds like a good alternative to my 3.5 Amp micro-USB power supply, but this supply doesn't overheat or undervoltage for me.

Your supply is superb;  the problem is the micro-usb connector;  it does not handle the necessary current well ( typically )

I have not seen a 'manufactured' euler bus powered solution;  and I don't expect to see it, frankly.  Making the necessary adjustment to the power line is trivial ( solder a female jumper connector to both leads of the power line and plug them into the appropriate pins on the euler bus ).

Read through the above link  ^^^   includes pics, and plans for PI filter ...

Thanks for the information.

I swear by these 3.5 Amp power supplies.  It was a stupid idea for all these SBC innovators to use micro-USB and USB OTG for power since so many people unknowingly use weak phone chargers and questionable power supplies that claim "2 Amp" and wonder why their kits don't work.

The Orange Pi folks had the right idea.  Their SBCs only use barrel connectors to reduce the chance of people using lame power supplies that cause undervoltage/undercurrent conditions that cause SDCard corruption and weird network problems (which my one-year-old original Kickstarter PINE A64+ has never experienced, nor have my many Orange Pis and Raspberry Pis with many fans and peripherals attached to them).

Thanks again.

I agree completely.  

... my own ABS Pine cases have barrel connectors ( all three of them ).  Internally I have the power line feed the euler bus according to my DC POWERIN link on the forum ( including the PI filter ).  On the outside the power feed comes in as a barrel connector ( the same one found on the Arduino Uno ).  You can get them from digikey and other suppliers like jameco. 

The micro-usb connector was a poor choice from an engineering standpoint; although, I understand why they chose it in terms of cost and ease of robotic installation. Its really too sad that the connector cannot handle the current necessary from an engineering standpoint.

Yeah, the entire SBC community has been harmed by the use of micro-USB connectors for power.  So many people report irreproducible problems with these things with the notable exception of the Orange Pi community, whose SBCs use barrel connectors exclusively. 

By the way, why it it called the "Euler" bus, anyway?
